'Theseteatures'are,

however, not claimed herein, "sincethey form 1 apartof'thesnbject-rnatter'of anotherapp'lication.

In machines embodying the constructions last he'reinbeforeilescribed, it is desirable, 1 in order to receive the "sheets at "one pointupon the cylinder and deliver the same from another point considerably distant from the point of reception, toprovide three sets "(if tapes, (see Figs. 3,)viz., twosets, 11 12, for carryihgthe sheets from the cutting-cylinders to the collecting-cylinder, one set, 1 1, of which extends around the cylinder to the point where the sheets are to be delivered from oh the cylinder, and a third set, 13, running over rollers "14 15 [6, covering that portion of the cylinder between thepoint of receptionto thepoint of delivery of the sheets. The cylinder, as'is readily understood,rnnst be encompassed by tapes in order to sustain the sheetsuponit;

and since these tapesmust travel'ih the same direction in which the cylinder'revolves, it is obvious that the tapes12eannot be extended over thespace covered bytheftapes 13, sin'ce 'theynecessarily travel in anbpposite direction.

The t portions of the cylinders not covered by theendless tapes, namelyythe sheet en-,

trance and exit points, areguarded by the "tapes, and guide the sheetsaround the cylin- "der. that their frontsurfaces coincide with the' 'surfaceof the tape-rollers 17, whereby'they assist The shape of those marked 2 is "suchinguiding the sheet from the tapes 11 onto the cylinder. Those marked 3 are hung on a rock-shaft, and have'a modeof operation hereinafter described.

In the arrangement herein "shown in Fig. 3,

the sheets are only partially severed from the web of paper by the cuttin g-cylinders 22 23, the portion left uncut at several pointsin-the 'widthof the sheet'being sufficientt'o support and guidethepaper 24 between the twb se- "ries 'of endless supply-tapes ll 12 that conduct the sheet to the grooved collecting-cylinder "30. 'This cylinder is caused to revolveturn for turn with the cuttingcylinders by means of bevel-gear connecting its shaft with that of one of the cutting-cylinders 22 23, it being understood that said cnttingcylinders are geared together. j v

The diameter of the collecting-cylinder is about one'and a half inch greater than the cutting-cylinders, which will cause the tapes ll 12 to travel somewhat faster than the paper, and, as the front edge of the partially-cut sheet arrives at the grooved roller 18, it is caught bythenip of the tapes 11 12 around the curve of said roller, and carried forward at an increased speed, and torn loose from the web. At this time the front edge of the sec .ond sheet has entered a sufficient distance between the tapes 11 '12 for them to support and carry it forward. In the meantime the j first sheet is carried on under the roller 17 to ,the grooved collecting-cylinder 30, the lower set of tapes 12 returning around the roller 18 p to the receiving-roller 20; but the upper tapes 11 pass round the cylinder 30 to the roller 21, and return by the roller 26 to the receivingroller19. The sheet is thus conducted by the tapes and fixed guide or deflector onto the sixth sheet is deposited upon it. As the collooting-cylinder 30 is, in diameter, one and a half inches larger than the cutting-cylinders,

its circumference is nearly five inches greater than the length of the sheets that are on it,

'. and this space of five inches is sufflcient to i allow the points of the deflectors or switches 3 to be moved into the grooves of the cylinder 30 behind the six sheets, and guide them off from the cylinder down in front of the flyframe 25, which will at that time be in position to receive them.

The deflector or switches3 are operated by a grooved cam, 4, formed on the inner side of .a spur-wheel, 5, keyed on the shaft 6. This wheel receives its motion from the pinion 7 on .one end of the shaft of the cylinder.

The pinion is to'the wheel in the proportion of one .to six, so that at every sixth revolution of the collecting-cylinder 30, the cylinder having received six sheets, the cam 4 moves the points of the switches in behind the six sheets, and

thus guides them off to the sheet-flyer, as is seen in Fig. 4.

The deflectors or switches 3 return back to .their original position intime to guide the ;next sheet on around the cylinder as before, as in Fig. 3.

On the opposite end of the shaft 6 is keyed the cam 36 that operates the fly-frame by means of the bell-crank lever 27 and connecting-rod 28, in the usual manner.

In order to surely drive the endless tapes 11 12 13, a toothed wheel, 8, is fixed upon the shaft of the collecting-cylinder 30, and gears into a pinion, 9,'on roller21, and into another, 10, on the roller 16. This gearing, together with the contact of the tapes with the'collecting-cylinder, insures their regular'and perfect action in conveying the sheets.

It will be seen that the number of sheets ing-cylinder.

This arrangement of the mechanism is pref erably employed when there is no obstacle to the height and length of the press necessitated by having the fly receive the sheets from the front side and lower surface of the cylinder.

When, however, it is desired to reduce the length of the press, the collecting-cylinder is made to revolve in the opposite direction, and the fly is made to operate so as to deliver the sheets in toward the printing-machine. The tape are thus disposed, as is seen in Fig. 5.

The tapes 12, which run in the right direction, are made to encompass about one-third of the circumference of the cylinder, while the tapes 11 are simply passed around pulleys 18 at one point of the circumference of the cylinder, and the tapes 13 encompass, as formerly, that portion of the cylinder between the points of the entrance and delivery of the sheets.

The two positions of the switch or deflector 3 are shown in Figs. 5 and 6.

The tape-rollers 16 21 are grooved (see Figs. 2, 3, 5, and 6) to admit the ends of the switches 3 into them as the switches are rocked to retain the sheets on the collecting-cylinder, or direct them off the same.

In like manner the tape-rollers 14 18 are grooved to receive the end of the fixed guides or deflector.

The collecting-cylinder is likewise grooved, (see Fig. 2,) to admit the toes of the switches or deflector.

It is obvious that the collecting-cylinder may be an endless carrier of any other con struction, such as tapes passed around two or more carrying-cylinders.

What is claimed is- 1. The combination of the collecting-cylinder 30 and endless tapes 11, 12, and 13, substantially as described.

2. The combination of the collecting-cylinder 30, endless tapes 11 12 13, and deflectors or switches 3, substantially as described.
